WOOD-SAWING MACHINE. n

Application led August 24, 1921.

ToaZZ whom t may concern: n

Be it known that 1, Lune CLARK, a citizen of the United States,`residing at La Salle, in the county of La Salle and Staterof Illinois7have invented new and useful Improvements in lVood-Sawing Machines, ofwhich the following is a specification.

My present invention pertains to wood sawing machines, and itcontemplates the provision of a device that is simple in constructionand one that may be easily operated by one person and this withoutliability of accident.

The invention also contemplates the provision of a wood sawing machinewhereby a large amount of wood may be quickly and expeditiously sawedand when occasion demands the blade of the device is capable of beingraised or lowered to permit pushing of the log on the` support therebyenabling the cutting of long or short lengths.

The invention in all of its details will be fully understood from thefollowing description and claim when the same are read in connectionwith the drawings, accompanying and forming part of this specifica-Vtion, in which:

Figure 1 is a top plan view of the sawing machine and showing thereceiving rollers and table of the machine.

Figure 2 is a longitudinal side elevation of the device.

Figure 3 is a sectional view similar to Figure 2 and showing the balancewheel in its raised and lowered positions.

Figure 4 is a sectional view of the frames that support the receivingrollers of the device.

Figure 5 is a detailed view showing the boxes ofthe main pulley shaftextending into the box of the main frame.

Similar numerals of reference designate corresponding parts of all ofthe views of the drawings.

My novel device comprises the frame 1 that rests on supports and issecured thereto in any approved manner and secured on the frame 1 bymeans of the straps 2 is a revoluble shaft 3 having a pulley 22 at theinner end thereof that derives rotary motion from a source of supply bymeans of the belt 23.

Adapted to be swung upwardly and down- Wardly on the shaft 3 andsupported on the in the collars 6 la balance wheel 21 and serial No.494,999.

frame l is a swinging frame 4 of angular form in cross section. Theframe 4 is provided with equi-distant straps 5 that receive revolubleshafts 7 and 19 that are arranged Figure 1.

The shaft 20 is provided at one endiwith at its inner end with a beveledgear or pinion 18 that meshes with the pinion 17 of the shaft 3, and theshaft 7 is also provided at one end with the pinion 8. that meshes withthe gear 17 "of `the shaft 3.

` At the inner end the frame 4 is provided with a shaft 10' having apinion 9 that meshes with an outer' pinion 8 of the shaft 7 and theshaft 10 is provided outside the frame 4, with the cutting saw 11 lthat`is tasses and 20 as illustrated in y splined or otherwise secured onthe shaft 10.

By reference to the drawings it will be seen that a frame 15 is arrangedon supports 16 and thisframe 15 is also secured on the support thatreceives the frame 1.

This frame 15 is provided with rollers to receive the log 12 and at itsinner the frame 15 is provided with the 13 that supports the log 12 inproper position during the cutting operation.

In the practical operation of the device the logs are fed on the rollers14 until they arrive at the proper `position o-n the table 13. Theangular frame 4 is then moved from the position shown in Figure 2 to theposition shown in dotted lines in Figure 3 by exerting pressure on thefoot-lever 24 that is provided wth the rod 25 which in turn is securedto the angular frame 4. This downward movement of the foot-lever 24will, in conjunction with the weight of the saw 11, easily move theframe t0 the cutting position. Power is applied to the shaft 3 throughbelt 23 and pulley 22. Rotary motion of the shaft 3 will be attended byrotary motion of the shafts 19 .and 7 which manifestly will impartrotary motion to the shaft 10 and in turn operate the blade 11. When alog or piece of lumber has been cut the blade may be lifted upwardly bydownward pressure on the counter-balance wheel 21 and hence the log bereadily positionedto receive the next operation of the blade. i

It will be noted from the drawing and particularly Figure 1 thereof,that the frame 14 end table vit becomes `necessary 15 is broken away atthe point where the blade 11 moves downwardly to bear against a log.

My invention is so constructed that even cutting of logs or other largeblocks of wood is assured at all times and this with but a minimumamount of effort on the part of those operating the device and becauseof the construction of the pinions and shafts and their relativearrangement with respect to the frame 4 adjustment of the blade may bemade without the necessity of cutting off the source of supply andenergy derived therefrom. This will be appreciated as quite an item whenit is considered that if for any reason to discontinue the cutting of alog the operation may -be susF pended by simply pulling down on thecounter-balance wheel and vhence the liability of accident to theoperator or the device is effectually precluded.

I would distinctly have it understood that I do not wish to 'confinemyself to the exact construction or relative arrangement of parts asspecified and illustrated, and this for the reason that such changes ormodifications may be made as fairly fall within the scope of the claimappended.

The main shaft as shown in Figure `5 has the boxes turned at their endsto extend into the box of the frame 2. Thus the boxes 4* will precludethe frame `carrying the saw from resting entirely on the shaft 3.

I'Iaving described my invention, what I claim `and desire to secure byLetters Patent In a wood sawing device the combination of supports, aframe mounted on the supports and a shaft upon which the frame isrocked, a pinion splined on the shaft, a shaft transverse to the firstnamed shaft having a pinion that-meshes with the pinion on the firstnamed shaft, a balance-wheel mounted on the opposite end of the secondnamed shaft, -a shaft extending in the same plane as the second namedshaft, pinions mounted on the ends of the last-named shaft; one of whichpinions meshes with the pinion on the first shaft and a shaft extendingparallel with the first shaft and having a pinion that meshes with oneof the pinions of the third named shaft, a cuttingblade secured on thelast named shaft and a log receiving frame and table.

In testimony whereof my hand in presence of nesses'.
